When I build an FreeRTOS example on github(https://github.com/MediaTek-Labs/mt3620_m4_software/tree/master/MT3620_M4_Sample_Code/FreeRTOS/MT3620_RTApp_FreeRTOS_CPP) There is an build error as below. and it seems that it's related to the FreeRTOS/portable/port.c

How can I fix this build error? Thanks.

@IvanLee-1,

Here are some notes on this error from a while back. You should find that the projects build under Visual Studio, but will see the issue when building with VS Code.

Note from a while back:

You can see my changes by going to my Forked Repo and my VsCodAndLinuxBuilds branch here: Avnet/mt3620_m4_software at VsCodAndLinuxBuilds (github.com). Look at the mt3620_m4_software/MT3620_M4_Sample_Code/FreeRTOS/MT3620_RTApp_FreeRTOS_UART example and you’ll see the following changes . . .

@bawilless ,

Thanks for your support. I confirmed that the FPU-related build error is solved on my side with your changes.

Thanks.
